Structural Equivalency Spreadsheet Requirements 2015

The side impact structure (SIS) for 2015requires three physical tests:

Entire SIS between front and main roll hoop up to a height of 350 mm ground must have a EI of 3 tubes (incl. vehicle floor)

SIS between the upper surface of the floor and 350 mm above the gro

least an EI of 2 tubes (without vehicle floor) and the vehicle floor itself

of 1 tube

SIS up to a height of 350 mm above the ground must at least absorb e

tubes (without vehicle floor)

Self made fasteners

Self made fastener are NOTprohibited, BUT:

Formula Student is an Engineering Design Competition

The first question is: How can we proof it?

At the Technical Inspection a team has to be able to show that the design and

material of the fasteners is according to the FSAE requirements (T11).

How? (3 things)

Design documentation / material certification (calculations) and

Mechanical tests (test documentation + test samples) and

Delivery note / invoice of the manufacturer
